THE EFFECT OF SIZE AND SHAPE OF SPECIMEN UPON THE UNCONFINED COMPRESSIVE STRENGTH OF CEMENT-STABILIZED MATERIALS

THE EFFECT OF THE SHAPE AND SIZE OF A TEST SPECIMEN UPON THE UNCONFINED COMPRESSIVE STRENGTH OF CEMENT- STABILIZED GRAVEL-SAND-CLAY, WELL-GRADED SAND, AND FINE CRUSHED ROCK ARE INVESTIGATED. A RANGE OF CEMENT CONTENTS WAS USED WITH EACH MATERIAL TO GIVE A RANGE OF STRENGTHS UP TO ABOUT 14 N/SQUARE MM. AT 7 DAYS. RELATIONSHIPS WERE OBTAINED BETWEEN THE STRENGTH OF CYLINDRICAL SPECIMENS OF DIFFERENT HEIGHT TO DIAMETER RATIOS AND BETWEEN THE STRENGTHS OF CUBES AND CYLINDRICAL SPECIMENS. THE AVERAGE RATIOS OF THE STRENGTH OF SPECIMENS WITH A HEIGHT: DIAMETER RATIO OF 1:1 WERE 0.89, 0.74 AND 0.65 FOR 150 MM, 100 MM AND 50 MM DIAMETER SPECIMENS RESPECTIVELY. THE AVERAGE RATIO FOR THE STRENGTH OF 150 MM CUBES TO THE STRENGTH OF 300 MM HIGH BY 150 MM DIAMETER CYLINDERS WAS 1.29, WHICH AGREES CLOSELY WITH THE VALUE OF 4/3 COMMONLY ACCEPTED FOR CONCRETE TEST SPECIMENS. /RRL/A/
